A noted exception to the general observation resulting from the existing historical records, that Thetis was not venerated as a goddess by cult, was in conservative Laconia , where Pausanias was informed that there had been priestesses of Thetis in archaic times, when a cult that was centered on a wooden cult image of Thetis (a xoanon ), which preceded the building of the oldest temple; by the intervention of a highly placed woman, her cult had been re-founded with a temple; and in the second century AD she still was being worshipped with utmost reverence. The Lacedaemonians were at war with the Messenians, who had revolted, and their king Anaxander, having invaded Messenia, took as prisoners certain women, and among them Cleo, priestess of Thetis. The wife of Anaxander asked for this Cleo from her husband, and discovering that she had the wooden image of Thetis, she set up the woman Cleo in a temple for the goddess. This Leandris did because of a vision in a dream, but the wooden image of Thetis is guarded in secret. 
4. The “dawn of man” introduction. This kind of introduction generally makes broad, sweeping statements about the relevance of this topic since the beginning of time, throughout the world, etc. It is usually very general (similar to the placeholder introduction) and fails to connect to the thesis. It may employ cliches–the phrases “the dawn of man” and “throughout human history” are examples, and it’s hard to imagine a time when starting with one of these would work. Instructors often find them extremely annoying.
